BACKGROUND
[0001] The present invention relates to an assembly comprising a storage chamber cover that
is mounted on a storage chamber for an adhesive and to a cloth bonding apparatus that
is provided with the storage chamber cover.
[0002] A cloth bonding apparatus bonds a cloth to a cloth with an adhesive instead of sewing
the cloths together with a needle and a thread. The cloth bonding apparatus is provided
with a storage chamber and a nozzle. The storage chamber stores the adhesive and melts
the stored adhesive by heating it. The nozzle discharges the adhesive that is melted
in the storage chamber and applies the adhesive between the two cloths. The cloth
bonding apparatus bonds the two cloths by pressing them together. Because the bonded
cloths have not been sewn together with the thread, there is no unevenness in the
bonded cloths.
[0003] The structures of the cloth bonding apparatus and the storage chamber are disclosed
in
JP 2010-222764 A. The cloth bonding apparatus raises the air pressure within the storage chamber,
extruding the adhesive and supplying it to the nozzle. The interior portion of the
storage chamber must therefore be sealed. The sealed storage chamber prevents drying
of the adhesive. The storage chamber has a shaft bearing at its upper end, and a cover
portion has a shaft portion. The cover portion turns around the shaft portion.
[0004] The storage chamber has an opening portion in its upper portion, and the cover portion
covers the opening portion.
SUMMARY
[0005] The opening portion in the upper portion of the storage chamber is only covered by
the plate-shaped cover portion. Therefore, the possibility exists that the interior
portion of the storage chamber cannot be reliably sealed. The temperature of the storage
chamber is raised to high, so an operator must wear heat-resistant gloves when the
operator opens and closes the plate-shaped cover portion. The heat-resistant gloves
are slippery. Therefore, it is difficult for the operator to open and close the cover
portion while wearing the heat-resistant gloves.
[0006] US 2008/0234120 A1 discloses a storage chamber and a storage chamber cover comprising a tube portion
and a top wall. Another storage chamber cover is known from
JP H08 175559 A.
[0007] The present invention provides an assembly in accordance with claim 1, comprising
a storage chamber cover that reliably seals the storage chamber and that can be mounted
and removed easily and safely, and a cloth bonding apparatus in accordance with claim
6 that is provided with the storage chamber cover.
[0008] This object is achieved by the assembly having the features of claim 1. The present
invention is further developed as defined in the dependent claims.
[0009] By rotating the storage chamber cover, an operator can firmly fix the screw cover,
which has been mounted to the inner side of the storage chamber cover, on the opening
portion of the storage chamber. Therefore, the operator can reliably seal off the
interior portion of the storage chamber. Because the storage chamber cover is positioned
on the outside of the screw cover, the temperature of the storage chamber cover is
lower than the temperature of the screw cover when the temperature of the storage
chamber is high. Therefore, the operator can fix and remove the screw cover more safely
than when the operator rotates the screw cover by touching the screw cover directly.
The tube portion of the storage chamber cover has the recessed portion that is recessed
toward the inside. The operator can rotate the storage chamber cover by placing his
fingers on the recessed portion, so his hand tends not to slip, even when he is wearing
the heat-resistant gloves. Therefore, the operator can easily and safely perform the
fixing and the removing of the screw cover.
[0010] The storage chamber cover may be provided with a vent hole formed on at least one
of the tube portion and the top wall. The storage chamber cover can discharge heat
from the inside to the outside through the vent hole. The temperature of the storage
chamber cover is lower than when the vent hole is not formed. Therefore, the operator
can perform work safely.
[0011] The storage chamber cover may be mounted on an upper portion of the storage chamber
such that the top wall covers the top of the storage chamber. The vent hole may be
formed in the top wall side in the recessed portion. Air that has reached a high temperature
rises in the storage chamber cover and escapes through the vent hole in the upper
portion of recessed portion. Therefore, the vent hole can efficiently inhibit any
rise in the temperature of the storage chamber cover. Dirt is less likely to enter
the interior of the storage chamber cover from the vent hole than in the case the
vent hole is formed in the top wall. The forming of the vent hole in the recessed
portion makes it easier for the operator's hand to get a hold in the recessed portion.
Therefore, the operator can perform work more easily and safely.
[0012] The storage chamber cover may be provided with a projecting portion that is formed
on an upper edge portion of the recessed portion to project in a direction away from
the central axis of the tube portion. When the operator carries the storage chamber
cover with his hand on the recessed portion, the operator's hand gets a hold on the
projecting portion. Therefore, it is harder for the operator to drop the storage chamber
cover.
[0013] The cover fixing portion may be provided with a fixing screw that is screwed into
a screw hole formed in the screw cover and with a rotation preventing portion that
fits together with one of a fixing concave portion and a fixing projecting portion
formed in the screw cover. The storage chamber cover can firmly fix the screw cover
with the fixing screw. The screw cover can be prevented from rotating in relation
to the storage chamber cover by engaging the rotation preventing portion with the
one of the fixing concave portion and the fixing projecting portion of the screw cover.
Therefore, the screw cover can be fixed more reliably than when the screw cover is
fixed to the storage chamber cover only by the fixing screw. If the operator tightens
the fixing screw after engaging the rotation preventing portion with the one of the
fixing concave portion and the fixing projecting portion of the screw cover, the screw
cover can easily be fixed to the storage chamber cover at the proper angle.
[0014] In a second aspect of this invention, a cloth bonding apparatus in accordance with
claim 6 is provided, which includes the storage chamber cover, the storage chamber,
and the screw cover described above, wherein cloths are bonded with an adhesive that
is stored in the storage chamber. Therefore, the cloth bonding apparatus provides
the same effects as the storage chamber cover. By using the cloth bonding apparatus,
the operator can perform the work of bonding the cloths safely and easily.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
[0016] Hereinafter, a storage chamber cover 60 according to an embodiment of the present
invention and a cloth bonding apparatus 1 that is provided with the storage chamber
cover 60 will be explained with reference to the drawings.
[0017] The configuration of the cloth bonding apparatus 1 will be explained with reference
to FIG. 1. The lower right side, the upper left side, the upper right side, and the
lower left side of the FIG. 1 respectively correspond to the front side, the rear
side, the right side and the left side of the cloth bonding apparatus 1. The cloth
bonding apparatus 1 is provided with a bed portion 2, a pillar portion 3, and an arm
portion 4. The bed portion 2 is mounted to a table (not shown in the drawings). The
pillar portion 3 extends vertically upward from the right end of the bed portion 2.
The arm portion 4 is connected to the upper end of the pillar portion 3, and projects
toward the left from the left side face of the pillar portion 3.
[0018] The bed portion 2 is provided with a lower feed roller, a lower feed motor, and the
like (not shown in the drawings) in its interior. The lower feed roller is positioned
directly below an upper feed roller 17 and drives a belt 18. The lower feed motor
drives the lower feed roller. The bed portion 2 serves as a base that supports the
pillar portion 3. The pillar portion 3 supports the arm portion 4. The arm portion
4 is provided with a beam portion 6, a storage portion 30, and a pump case 20, in
order starting from the rear. The arm portion 4 is provided with various types of
motors and the like in its interior.
[0019] The beam portion 6 will be explained. The beam portion 6 is provided with a body
portion 7, a spring support portion 8, and a column portion 9. The body portion 7
is a roughly rod-shaped member, and it extends in a horizontal direction to the left
from the left rear edge of the arm portion 4. The spring support portion 8 is plate-shaped
and extends in a horizontal direction toward the front from the left end of the body
portion 7. The column portion 9 extends diagonally downward toward the front from
the body portion 7 at an angle of approximately 45 degrees from the horizontal plane.
The lower end portion of the column portion 9 does not contact with the bed portion
2.
[0020] The spring support portion 8 has a hole in its front end portion. An upper end portion
of a shaft portion 12 is inserted into the hole, such that the spring support portion
8 supports the shaft portion 12 such that the shaft portion 12 can move up and down.
The shaft portion 12 is inserted through a spring 11. The column portion 9 has a shaft
on the left side of its lower end that extends in the left-right direction. The column
portion 9 support a rear end portion 14 of a roller holding portion 13 by the shaft.
The roller holding portion 13 can pivot around the shaft such that a front end portion
15 moves in the up-down direction.
[0021] The roller holding portion 13 support the upper feed roller 17 rotatably by the front
end portion 15. The upper feed roller 17 is positioned close to and to the rear of
a cylindrical nozzle 25. The roller holding portion 13 has a shaft support portion
16 on its upper side, slightly toward the front from the center. The shaft support
portion 16 supports the lower end of the shaft portion 12 that has been inserted through
the spring 11. The spring 11 is located between the spring support portion 8 and the
lower end of the shaft portion 12. The spring 11 energizes the roller holding portion
13 downward by energizing the shaft portion 12 downward. The upper feed roller 17
and the belt 18 move a cloth in the front-rear direction by rotating with the cloth
pressed between them.
[0022] The pump case 20 will be explained. The pump case 20 is provided with a first pump
case 21 and a second pump case 22. The first pump case 21 has a roughly cubic shape
and is connected by four screws to the left side face of the arm portion 4. The left
side of the first pump case 21 forms a recessed portion, and a gear pump (not shown
in the drawings) is provided in the recessed portion. The second pump case 22 is connected
by four screws to the left side of the first pump case 21 and covers the gear pump.
The first pump case 21 and the second pump case 22 form a pump chamber. The gear pump
receives from the storage portion 30 an adhesive that the storage portion 30 has melted
by heating and supplies an appropriate amount of the adhesive to the nozzle 25 under
pressure.
[0023] The bottom portion of the second pump case 22 holds a support portion 24. The support
portion 24 extends toward the left from the bottom portion of the second pump case
22 and bends downward at its left end. The bottom end portion of the support portion
24 is slightly separated from the top surface of the bed portion 2. The bottom end
of the support portion 24 holds the rod-shaped nozzle 25. The nozzle 25 projects toward
the left from the support portion 24. The direction in which the nozzle 25 projects
may also be toward the right. The support portion 24 is provided with a feeding channel
(not shown in the drawings) in its interior. The feeding channel extends from the
gear pump to the nozzle 25. The nozzle 25 discharges the adhesive that has passed
through the feeding channel. The pump case 20 and the support portion 24 are provided
with heaters (not shown in the drawings) in their interiors. The heaters heat the
adhesive that passes through the pump case 20 and the support portion 24. Therefore,
the adhesive that the storage portion 30 has heated does not harden on its way to
the nozzle 25.
[0024] The storage portion 30 has a roughly rectangular shape whose long direction is the
up-down direction. The storage portion 30 extends vertically upward from the left
side of the arm portion 4 and the rear side portion of the pump case 20. The storage
portion 30 is mainly provided with a storage chamber 31, the storage chamber cover
60, and a screw cover 44 (refer to FIG. 3).
[0025] The storage portion 30 will be explained with reference to FIGS. 2 to 4. In order
to facilitate the explanation, a square tube-shaped outer frame of the storage chamber
31 is not shown in FIGS. 2 to 4. The storage chamber cover 60 is mounted on the upper
portion of the storage chamber 31. In order to melt the adhesive that is stored in
its interior, the temperature of the storage chamber 31 is increased by using heat
from a storage chamber heater (that is described later). The storage chamber cover
60 is formed from a synthetic resin that has lower thermal conductivity than metal.
Therefore, mounting the storage chamber cover 60 on the storage chamber 31 prevents
the operator from being burned by directly touching the high-temperature storage chamber
31. As shown in FIGS. 3 and 4, the screw cover 44 is fixed to the interior of the
storage chamber cover 60. The screw cover 44 is mounted on the upper portion of the
storage chamber 31 by being screwed onto it. Therefore, the operator can mount the
screw cover 44 and the storage chamber cover 60 on the upper portion of the storage
chamber 31 at the same time simply by rotating the storage chamber cover 60.
[0026] The storage chamber 31 will be explained. The storage chamber 31 is provided with
a cartridge holding portion 32, leg portions 33, and an opening portion 39.
[0027] The cartridge holding portion 32 is a cylindrical member. The operator sets a cylindrical
cartridge 37 that is filled with the adhesive in the cartridge holding portion 32
by inserting the cartridge 37 into an opening in the upper portion of the cartridge
holding portion 32. The cartridge holding portion 32 has a screw hole 35 in each of
the right rear and the left front of its upper end for fixing the opening portion
39 in place. The cartridge 37 is provided with a ring-shaped packing 52 on its bottom
face (the face at its upper end in FIG. 3).
[0028] The leg portions 33 are formed on the right front side, the right rear side, the
left front side and the left rear side of the outer circumferential face of the cartridge
holding portion 32. The leg portions 33 extend from the bottom end of the cartridge
holding portion 32 to the center in the up-down direction. The leg portions 33 hold
the orientation of the cartridge holding portion 32. The leg portions 33 on the right
front side and the left rear side each have a heater insertion hole 34 that extends
in the up-down direction. Each one of the heater insertion holes 34 holds one of the
rod-shaped storage chamber heaters (not shown in the drawings) in its interior. The
cloth bonding apparatus 1 melts the adhesive that is inside the cartridge 37 by supplying
electricity to the storage chamber heaters.
[0029] The opening portion 39 is cylindrical. The opening portion 39 has two helical grooves
40 in its outer circumferential face for mounting the screw cover 44. The shapes of
the helical grooves 40 are axially symmetrical around the central axis of the opening
portion 39. The bottom end portion of the opening portion 39 is provided with a flange
portion 41 that is rectangular in a plan view. The flange portion 41 has a screw hole
42 in each of its right rear corner and its left front corner. The opening portion
39 is fixed in place on the upper portion of the cartridge holding portion 32 by aligning
the positions of the two screw holes 42 in the flange portion 41 with the positions
of the two screw holes 35 in the cartridge holding portion 32 and fastening the aligned
screw holes together with screws. The central axis of the cylindrical opening portion
39 is aligned with the central axis of the cartridge holding portion 32.
[0030] The screw cover 44 will be explained. As shown in FIG. 3, the screw cover 44 is provided
with a circumference wall portion 45, an upper portion blocking portion 50, and an
air line connecting portion 54.
[0031] The circumference wall portion 45 is cylindrical. The inside diameter of the circumference
wall portion 45 and the outside diameter of the opening portion 39 of the storage
chamber 31 are equal. As shown in FIG. 4, the circumference wall portion 45 is provided
with two lug portions 46 on its inner face. The two lug portions 46 project toward
the inside of the circumference wall portion 45. The two lug portions 46 are formed
in positions that are symmetrical in relation to the central axis of the circumference
wall portion 45. The operator can mount the screw cover 44 on the opening portion
39 by fitting each of the two lug portions 46 into the corresponding one of the two
helical grooves 40 and rotating the screw cover 44 clockwise in a plan view. The operator
can remove the screw cover 44 from the opening portion 39 by rotating the screw cover
44 counterclockwise in a plan view. As shown in FIG. 3, the circumference wall portion
45 is provided with two slotted pieces 47 and two unslotted pieces 48 on the edge
of its upper end. The top faces of the unslotted pieces 48 are flat. A slot-shaped
fixing slot portion 49 is formed in the top face of each of the slotted pieces 47.
The operator can easily fix the storage chamber cover 60 and the screw cover 44 in
place using the slotted pieces 47 and the unslotted pieces 48. This will be explained
in detail later.
[0032] The upper portion blocking portion 50 is a roughly disc-shaped member with a recessed
lower side. The upper portion blocking portion 50 is provided with a connecting portion
51 in the center of its top face. The connecting portion 51 guides air into the interior
of the cartridge 37 from an air line (not shown in the drawings) that supplies compressed
air. The force of the compressed air moves the adhesive in the interior of the cartridge
37 toward the gear pump inside the pump case 20 (refer to FIG.
[0033] 1). As shown in FIG. 4, the upper portion blocking portion 50 is fixed in place on
the upper portion of the circumference wall portion 45. The upper portion blocking
portion 50 is provided, in the center of its bottom face, with a needle 53 whose lower
end projects sharply. When the screw cover 44 is mounted on the opening portion 39,
the needle 53 penetrates to the inner side of the packing 52 of the cartridge 37 and
makes a hole in the bottom face of the cartridge 37. The hole serves as an inflow
channel for the compressed air into the interior of the cartridge 37. At the same
time, the packing 52 of the cartridge 37 blocks the gap between the cartridge 37 and
the screw cover 44. The air line connecting portion 54 is connected to the air line
(not shown in the drawings) and is fitted onto the connecting portion 51 from above.
[0034] The storage chamber cover 60 will be explained. As shown in FIG. 2, the shape of
the storage chamber cover 60 is roughly that of a square tube that is closed at its
upper end. The storage chamber cover 60 is provided with a tube portion 61 and a top
wall 62. The length of one side of the upper portion of the tube portion 61 is slightly
shorter than the length of one side of the lower portion. In a state in which the
storage chamber cover 60 has been mounted on the storage chamber 31, the tube portion
61 covers the outer circumferential face (the side face) of the upper portion of the
storage chamber 31. The top wall 62 is formed in an opening at the top of the tube
portion 61. In the state in which the storage chamber cover 60 has been mounted on
the storage chamber 31, the top wall 62 blocks the upper end of the storage chamber
31. Therefore, the storage chamber cover 60 reliably prevents the operator from directly
touching the upper portion of the high-temperature storage chamber 31. The top wall
62 has a circular air line insertion hole 72 in its center. The air line insertion
hole 72 allows the air line (not shown in the drawings) to pass into the interior.
Arrows 73 that indicate the direction of rotation for removing the screw cover 44
are formed on the top wall 62 around the air line insertion hole 72. By looking at
the arrows 73, the operator can easily determine the direction of rotation for removing
the screw cover 44.
[0035] The storage chamber cover 60 is mainly provided with recessed portions 63 to 66,
vent holes 68, projecting portions 70, and cover fixing portions 75.
[0036] The recessed portions 63 to 66 will be explained. As shown in FIGS. 2, 5, and 6,
the tube portion 61 includes a front recessed portion 63, a rear recessed portion
64, a right recessed portion 65, and a left recessed portion 66 (hereinafter collectively
called the recessed portions 63 to 66), with shapes that are recessed toward the inside.
The front recessed portion 63 is formed on the front face of the tube portion 61,
the rear recessed portion 64 is formed on the rear face, the right recessed portion
65 is formed on the right face, and the left recessed portion 66 is formed on the
left face. The shapes of the recessed portions 63 to 66 are shapes that are curved
smoothly toward the inside. The shapes of the four recessed portions 63 to 66 are
all the same except for the presence or absence of the vent holes 68, which will be
described later. The recessed portions 63 to 66 are formed such that they extend toward
the upper end of the tube portion 61 from slightly below the centers of the four faces
of the tube portion 61.
[0037] When the operator rotates the storage chamber cover 60 by hand, the operator can
place his fingers in the recessed portions 63 to 66 and the palm of his hand on the
corners of the tube portion 61. Therefore, the operator can easily grasp the corners
of the tube portion 61 and rotate the storage chamber cover 60. Even when the operator
is wearing heat-resistant gloves, the operator can easily and safely perform the mounting
and the removing of the storage chamber cover 60 and the screw cover 44.
[0038] The vent holes 68 will be explained. As shown in FIGS. 2, 5, and 6, the storage chamber
cover 60 has at least one of the vent holes 68 on at least one side of the tube portion
61 and the top wall 62. Air whose temperature has been raised by the heating of the
storage chamber 31 passes through the vent holes 68 and flows to the outside of the
storage chamber cover 60. Therefore, the temperature of the storage chamber cover
60 is lower than if the vent holes 68 are not formed. The operator can perform work
more safely.
[0039] The storage chamber cover 60 according to the present embodiment has the vent holes
68 in the tube portion 61 and not in the top wall 62. Therefore, the vent holes 68
face toward the side. Because the vent holes 68 in the storage chamber cover 60 face
toward the side, the possibility is reduced that dirt that falls from above will penetrate
into the interior of storage chamber cover 60 through the vent holes 68. As shown
in FIGS. 5 to 7, the storage chamber cover 60 has five of the vent holes 68 in each
of the upper edge portion of the right recessed portion 65 and the upper edge portion
of the left recessed portion 66. Air that has reached a high temperature rises in
the interior of the storage chamber cover 60. Therefore, the storage chamber cover
60 can flow the high-temperature air efficiently to the outside through the vent holes
68 in the top wall 62 side of the tube portion 61 (in the upper portion of the tube
portion 61).
[0040] As described previously, the operator places his fingers in the recessed portions
63 to 66 when the operator rotates the storage chamber cover 60. The operator's fingers
can easily be placed in the areas of the right recessed portion 65 and the left recessed
portion 66 where the vent holes 68 have been formed. Therefore, the operator can easily
and safely perform the mounting and the removing of the storage chamber cover 60 and
the screw cover 44.
[0041] When the storage chamber cover 60 is rotated until the lug portions 46 (refer to
FIG. 4) come into contact with the ends of the helical grooves 40, the front recessed
portion 63 stops such that it faces the front side. The operator performs work at
the front side of the cloth bonding apparatus 1. The storage chamber cover 60 has
the vent holes 68 in the right recessed portion 65 and the left recessed portion 66,
and does not have the vent holes 68 in the front recessed portion 63. Therefore, the
storage chamber cover 60 can keep the operator out of the high-temperature air that
has been discharged from the vent holes 68 to strike the operator who is performing
work at the front side.
[0042] The projecting portions 70 will be explained. As shown in FIG. 8, the storage chamber
cover 60 is provided with the projecting portions 70 at the upper edges of the recessed
portions 63 to 66 (only the recessed portions 65, 66 are shown in FIG. 8). The projecting
portions 70 project in the direction away from the central axis (toward the outer
side) of the tube portion 61. When the operator carries the storage chamber cover
60 with his hand on the recessed portions 63 to 66, the operator's hand gets a hold
on the projecting portions 70. Therefore, the projecting portions 70 can reduce the
possibility that the operator will drop the storage chamber cover 60, even when the
operator is wearing the slippery heat-resistant gloves. As shown in FIGS. 7 and 8,
the projecting portion 70 at the upper edge of the right recessed portion 65 and the
projecting portion 70 at the upper edge of the left recessed portion 66 are formed
at the upper edges of the vent holes 68. Therefore, the projecting portions 70 can
reduce the possibility that dirt will enter through the vent holes 68.
[0043] The cover fixing portions 75 will be explained. As shown in FIGS. 5 and 6, the storage
chamber cover 60 is provided with the cover fixing portions 75 at the right front
side, the right rear side, the left front side, and the left rear side. The cover
fixing portions 75 fix the screw cover 44 to the storage chamber cover 60.
[0044] FIG. 9 is a vertical sectional view of the cover fixing portion 75 at the right front
side of the storage chamber cover 60. The cover fixing portion 75 is provided with
a concave portion 76, a screw hole 77, and a fixing screw 85. The concave portion
76 is a portion that is concave downward from the wall surface of the top wall 62.
The screw hole 77 is formed in the bottom portion of the concave portion 76. The metal
fixing screw 85 fixes the screw cover 44 to the storage chamber cover 60 by fastening
the screw hole in the slotted piece 47 of the screw cover 44 (refer to FIG. 3) to
the screw hole 77 of the concave portion 76. Once the screw cover 44 is fixed to the
storage chamber cover 60, the axis of rotation of the screw cover 44 is aligned with
the central axis of the tube portion 61 of the storage chamber cover 60. Because the
screw hole 77 is formed in the bottom portion of the concave portion 76, the head
of the fixing screw 85 is not exposed on the surface of the top wall 62. It is therefore
difficult for the operator to touch the metal fixing screw 85, which has high thermal
conductivity, so the possibility that the operator will be burned is reduced.
[0045] As shown in FIG. 9, the concave portions 76 at the right front side and the left
rear side of the storage chamber cover 60 are provided with rotation preventing portions
80 at their lower ends. The rotation preventing portions 80 are projecting portions
that project farther downward from the lower ends of the concave portions 76. The
rotation preventing portions 80 engage into the fixing concave portions 49 that are
formed in the slotted pieces 47 of the screw cover 44. Engaging the rotation preventing
portions 80 into the fixing concave portions 49 prevents the screw cover 44 from rotating
in relation to the storage chamber cover 60. Therefore, the screw cover 44 can be
fixed more reliably than when the screw cover 44 is fixed to the storage chamber cover
60 only by the fixing screws 85. The operator fastens the fixing screws 85 after fitting
the rotation preventing portions 80 into the fixing concave portions 49, so the screw
cover 44 can easily be fixed to the storage chamber cover 60 at the proper angle.
[0046] As shown in FIG. 6, of the four cover fixing portions 75, the cover fixing portions
75 at the right front side and the left rear side of the storage chamber cover 60
have the rotation preventing portions 80. The cover fixing portions 75 at the right
rear side and the left front side of the storage chamber cover 60 do not have the
rotation preventing portions 80. Therefore, the shape of the storage chamber cover
60 is axially symmetrical around the central axis of the tube portion 61. As explained
previously, the screw cover 44 is provided with the slotted pieces 47 at the right
front side and the left rear side and is provided with the unslotted pieces 48 at
the right rear side and the left front side. The rotation preventing portions 80 engage
with the fixing concave portions 49 of the slotted pieces 47 only when the storage
chamber cover 60 is adjusted to the predetermined angle in relation to the screw cover
44. When the rotation preventing portions 80 fits into the fixing concave portions
49, the storage chamber cover 60 is in the appropriate orientation, where the vent
holes 68 face the right side and the left side. Therefore, the operator can easily
fix the screw cover 44 to the storage chamber cover 60 by adjusting the orientation
of the storage chamber cover 60.
[0047] According to the present embodiment, by rotating the storage chamber cover 60, the
operator can firmly mount the screw cover 44, which has been fixed to the inner side
of the storage chamber cover 60, on the opening portion 39 of the storage chamber
31. Therefore, the operator can reliably seal off the interior portion of the storage
chamber 31. Because the storage chamber cover 60 is positioned on the outside of the
screw cover 44, the temperature of the storage chamber cover 60 is lower than the
temperature of the screw cover 44 when the temperature of the storage chamber 31 is
high. Therefore, the operator can mount and remove the screw cover 44 more safely
than when the operator rotates the screw cover 44 by touching the screw cover 44 directly.
The tube portion 61 of the storage chamber cover 60 has the recessed portions 63 to
66 that are recessed toward the inside. The operator rotates the storage chamber cover
60 by placing his fingers on the recessed portions 63 to 66, so his hand tends not
to slip, even when he is wearing the heat-resistant gloves. Therefore, the operator
can easily and safely perform the mounting and the removing of the screw cover 44.
[0048] Various modifications can be made to the embodiment that is described above. For
example, the tube portion 61 may be a round tube instead of a square tube. Even when
the tube portion 61 is a round tube, the operator can easily rotate the storage chamber
cover 60 by placing his hand on the recessed portions 63 to 66 that are formed in
the side faces of the tube portion 61. The number, the shapes, and the like of the
recessed portions 63 to 66 can be modified. For example, the shapes of the recessed
portions 63 to 66 do not have to be curved smoothly toward the inside. The recessed
portions 63 to 66 may also extend from the upper edges to the lower edges of the wall
surfaces of the tube portion 61. The recessed portions 63 to 66 may also be formed
such that only the central portions of the wall surfaces are recessed. The storage
chamber cover 60 may also have the recessed portions only on the right side face and
the left side face of the tube portion 61.
[0049] The structure for fixing the screw cover 44 to the storage chamber cover 60 may also
be modified. For example, the screw cover 44 may also be fixed to the storage chamber
cover 60 using clips or the like instead of the fixing screws 85. It is not necessary
for the central axis of the tube portion 61 of the storage chamber cover 60 to be
aligned to the axis of rotation of the screw cover 44, as long as it is parallel to
the axis of rotation of the screw cover 44. Even if the axis of rotation of the tube
portion 61 and the axis of rotation of the screw cover 44 are not aligned, the operator
can perform the mounting and the removing of the screw cover 44 by rotating the storage
chamber cover 60.
[0050] The shapes, the positions, the number, and the like of the vent holes 68 can be modified.
For example, the vent holes 68 may also be formed in the top wall 62. The vent holes
68 may also be formed in any location other than the recessed portions 63 to 66 of
the tube portion 61. It is preferable for the vent holes 68 to be formed in the upper
edge portions of the recessed portions 65, 66, but the vent holes 68 may also be set
apart from the upper edge portions. The storage chamber cover 60 may also have a single
horizontally long hole instead of the five vent holes 68.
[0051] In the embodiment that is described above, the rotation preventing portions 80 have
projecting shapes, and the fixing concave portions 49 of the screw cover 44 have slot
shapes. Conversely, the rotation preventing portions 80 may have slot shapes, and
the screw cover 44 may be provided with fixing projecting portions. The recessed portions
that form the slotted pieces 47 do not have to be slot-shaped. The recessed portions
may be any shape that fits together with the rotation preventing portions 80.
